Regional tracts of land where the geology is permissive for the occurrence of undiscovered porphyry copper deposits, with probabilistic estimates of undiscovered resources, along with tables of discovered deposits and prospects.
Includes deposits, occurrences, and prospects; drill core logs and measured sections; and spatial databases for geologic maps, untested exploration areas, and permissive tracts for undiscovered mineral deposits.
Multi-element geochemical analysis of host rock, ore, mine waste, flotation-mill tailings, slag, stream sediments, creek and adit waters, and leachates of mine waste and mill tailings.
Probabilistic estimates of the amounts of undiscovered gold, silver, copper, lead, and zinc in conventional types of mineral deposits in the United States.
Chemical analysis of surface samples taken over a well known but concealed deposit to understand metal migration into the surface materials and to assess the power of surface sampling for detecting concealed deposits of this type.
Report on known and undiscovered nonfuel mineral deposits and resources of the Asia and Pacific region. Includes the age and type of rocks that contain the deposits, and regional exploration history.
Initial results of a petrographic, geochemical, and isotopic study of Mesozoic intrusive rocks and spatially associated Zn-Pb-Ag-Cu-Au prospects in the area.
These regional reports are designed to inform the non-earth scientist about the regional locations and general geologic setting of known deposits of major nonfuel mineral commodities.
